Kanchanaburi is a city at the confluence of the Rivers Kwai Noi and Kwai Yai. For most visitors the main sight of interest is the Bridge over the River Kwai, as the start of the infamous World War II Death Railway to Burma (now Myanmar), as well as the many associated museums. 

There is an increasingly thriving backpacker scene taking advantage of the chilled-out riverside vibe for those who want to get away from Bangkok. Kanchanaburi is also the gateway to the surrounding province of the same name. More foreign visitors are discovering why Thais know it as one of the most beautiful provinces in the country with its easily accessible waterfalls and national parks.

The area northwest of Kanchanaburi is dominated by beautiful River Kwai valleys. It is an area of great natural beauty, with a dazzling number of waterfalls, caves, lakes, and mountainous scenery. Most attractions can be visited as a day-trip from Kanchanaburi.
